HERBERT HASTINGS, OF ROCHESTER; NEW YORK, ASSIGNOR TO ART IN BUTTONS,

- INCORPORATED, A CORPORATION OF NEW YORK.

FEEDING TABLE FOR BUTTON-BLANKS.

To all whom it may concern;

State of New Yorlnhave inventedcertain new and useful Improvements inFeeding- Tables for Button-Blanks; and I: do hereby declare thefollowingto be a full. clear, and exact description of the same, reference beinghad to the accompanying drawings, forminga part of this specification.and to the reference-numerals marked thereon.

M present invention relates to a feeding table for button blanksand hasfor its'object to provide means for holding a plurality of spaced buttonblanks in proper position for delivery to a series of work piece holdersthrough the medium of any suitable transferring mechanism. i I

A furtherfobject of the invention is to provide adjustable means forholding differentsize blanks in position upon a feed table for deliveryto a series ofwork piece holders of any approved type. To these andother ends the invention consists in certain improvements andcombinations of parts, all as will be hereinafter more fully described,the novel features being pointed out in the claims at theend of thespecification.

In the drawings:

Figure 1 is a plan view illustrating one embodiment of my invention;

Fig. 2 is a similar view with certain'parts removed to more clearlyillustrate the mechanism for properly centering the work pieces upon thetable;

Fig.3 is an enlarged sectional view taken on line aa of Fig. 1, and

Fig. 4 is a sectional view taken on line bb of Fig. 1. y

Similar reference characters in the several figures indicate the sameparts.

Illustrating the present embodiment 'of the invention I preferablyprovide alfeeding table for button blanks as indicated at 10, upon whichthe workpieces or button blanks, previously prepared and assorted,

are positioned by an attendant.

l The feeding table -is provided ,Wl'fh equidistantly spaced 'notches 11over which'the centers of the blanks, such as 12, are placed and heldbypressure'of spring fingers 13.

Specification of Letters Patent. Patented Oct, 22, 1918,

Application filed November is, 1915. SerialNo. 61,839.

to the periphery of the latter, the table is provided with centeringdevices or spacers which may be adjusted in accordance with thesize andcharacter of the button blank stock to be operated upon. Thecentralporlar hub or shoulder 14 surrounded by a ring 15 having outwardlyprojecting gage fingers 16, located between the slots 11 in the table.Also journaled on the hub, above the plate 15, is a ring 17 providedwith a plurality of notches 18 which receive the short arms 19 20 on theplate 21. at the base of each cage finger 16. The arms 22 of each of thebell crank levers extend laterally from their re spectivegage fingersacross the slots 11 in the feeding table and are movable inwardly andoutwardly, by an oscillatory movement of the ring 17 to vary thedistance between them and between the edge of the table wherebydiiferent size blanks may be acto position the gave .fingers 16laterally relatively to the slots in the table and the latter to movethe fingers 22 inwardly or outwardly on the face of the table. I Thelever for ad usting the plate 15 is indicated by 25 and is pivoted atthe point 26 on one of the pivot pins 20, and is provided with anelongated aperture 27 into which extends a p n 28 projecting outwardlyfrom the'plate 15 through a slot 29 in the ring 17 and a correspondingaperture in the plate21. The

inner end of the lever 25 is slotted at 30 and cooperates with aclamping screw 31. The point 26 being stationary an oscillatory movementof the lever 25 will cause the lowermost ring 15 to be shifted back andforth. A similar lever 32 is pivoted at 33 on another of the pivot pins20 and cooperates with the pin 34 on the intermediate ring 17 tooscillate the latter whereby all of the bell crank arms 22 may besimultaneously tion of the table is provided with an annuof small bellcrank levers pivoted on pins adjusted toward or from their respectivetable slots 11. This lever is also secured in operative position by aclamping screw 35. The feeding table is mounted n a horizontal positionupon the upper end of a vertical shaft 36 operatively connected with aportion of a button turning machine (not shown), with which said feedingmechanism coiiperates.

Arranged at one side of the feeding table 10 is a platform 3? on whichquantity of the button blanks may be retained. The surface of thisplatform lies in the plane of the upper face of the feeding table andits adjacent edge is curved and arranged in juxtaposition thereto, sothat the button blanks may be readily transferred from the platform intoproper position on the feeding table and adjusted by the attendantbeneath the springs 13 and in engagement with the gage fingers 16 and22.

I claim as my invention:

3. In a blank feed table for button n1a ing machines, the combinationwith an annular plate having its periphery provided with spaced notches,and a central project ing hub portion,.oi a ring surrounding the hub andprovided with fingers corresponding to said notches, a pivoted lever armand an operating connection between it and said ring to adjust thelatter and simultaneously move its several fingers relatively to theirrespective notches.

4 in a blank teed table, the combination with an annular plate and aring thereon having outwardly extending spaced fingers, of blankcentering members above said ring and adjustable outwardly relatively tothe fingers.

5. In a blank feed table for automatic machines for operating upon blankwork pieces, the combination with an annular plate provided with aplurality of spaced notches in its periphery, a plate overlying it andhaving fingers arranged between said notchesand forming side gagemembers and means for adjusting them relatively to the notches, ofcentering gage members above the notches and adjustable inwardly andoutwardly relatively thereto.
